Self-assembly of metal nanoparticles has applications in the fabrication of optically active materials. Here, we introduce a facile strategy for the fabrication of films of binary nanoparticle assemblies. Dynamic control over the configuration of gold nanorods and nanospheres is achieved via the melting of bound and unbound fractions of liquid-crystal-like nanoparticle ligands. This approach provides a route for the preparation of hierarchical nanoparticle superstructures with applications in reversibly switchable, visible-range plasmonic technologies.
金属纳米颗粒的自组装在光学活性材料的制造中有应用。在此，我们介绍一种用于制备二元纳米颗粒组装体薄膜的简便策略。通过熔化液晶状纳米颗粒配体的结合部分和未结合部分，实现了对金纳米棒和纳米球构型的动态控制。这种方法为制备具有可逆切换的可见范围等离子体技术应用的分级纳米颗粒超结构提供了一条途径。
